Vodacom bad service

I'm not sure I should bother, after seeing all the bad reviews on Hello Peter. I have ordered a new phone from Vodacom in Benoni. For the past three weeks I have phoned them twice a week, the mandatory (we will phone you when the phone arrives) did not happen, and all I'm being told is sorry the phone has not arrived yet. Today I was told to contact head office maybe they will do something about it, our manager here is not going to do anything. Such a pity we pay to get such bad service.
